Answer 2

Problem Analysis

We are given the following information: - Peter (Petya) is chasing Sergey (Serёzha), who is walking at a speed of 100 m/min. - The current distance between them is 300 meters. - Peter's speed is 160 m/min.

We need to determine how many minutes it will take for Peter to catch up with Sergey.

Solution

To solve this problem, we can use the formula:

Time = Distance / Speed

Let's calculate the time it will take for Peter to catch up with Sergey.

1. Calculate the time it would take for Sergey to cover the distance of 300 meters at his speed of 100 m/min:

Time taken by Sergey = Distance / Sergey's speed = 300 m / 100 m/min = 3 minutes.

2. Since Peter is chasing Sergey, he needs to cover the same distance in less time. Let's calculate the time it would take for Peter to cover the same distance at his speed of 160 m/min:

Time taken by Peter = Distance / Peter's speed = 300 m / 160 m/min = 1.875 minutes.

However, we need to convert this time to minutes and seconds. Since 0.875 minutes is equal to 52.5 seconds, we can round it to 53 seconds.

Therefore, the total time it will take for Peter to catch up with Sergey is approximately 1 minute and 53 seconds.

Answer

Peter will catch up with Sergey in approximately 1 minute and 53 seconds.
